SimCenter Forum

Hi! I am new to R2D and I am still learning the ropes, but I am having several issues when running the Example 1 Basic Hazus.

First, when I run it locally on the computer, it gives me the error "Python version 3.8 or 3.9 is required, you have Python version 3.9 installed". I saw some previous posts with this same problem, but the answer seemed to be that the next version would fix this bug, however I am here over a year later from that previous post with this same problem. Should I just download version 3.8? The weird thing is though it was working for me, I was able to get results from running it locally and then apparently all of a sudden one day it just started giving me that error.

My second issue is one other people have had before too; when I run it at DesignSafe, the status of the job is blocked and I am unable to download results. From reading the responses, it seems they are always asked what the Tapis ID under preferences is, so here is mine "rWhale-stampede-3.1.0u1". I wasn't sure what to do to fix it though.

Thank you!

Hi Bofan,

Thanks for using the SimCenter forum.

To better understand the issue. Can you share the "GroundMotions" folder in your SimCenter LocalWorkDir/HazardSimulation folder with me?

Thanks and regards,

Hello,

If you add the three lines at the bottom of this message before Line 295 in the link I sent you in my previous reply, You will be able to set the location of the hypocenter.

Please note that 1. These lines set the location of the hypocenter but not the epicenter. The hypocenter needs to be defined on the fault surface with a depth, and you can add "print(rupSurface.getEvenlyDiscritizedListOfLocsOnSurface().toString())" before Line 295 to check the geometry of the fault surface. 2. The hypocenter defined here is only used by Cambell & Bozorgnia (2014) ground motion models and nowhere else in the backend calculation. If you would like to define the hypocenter for other use, please let us know, and we will see how we can help.

Hope this is clear.

rup = rupList.get(rupture_index)
rup.setHypocenterLocation(Location(33.97, -117.91 , 0))
rupList.set(rupture_index, rup)

Hello,

Thanks for using the SimCenter forum.

Defining the location of hypocenter is not available through editing the configuration Json file, but it is possible by editing the SimCenterBackendApplication python code at https://github.com/NHERI-SimCenter/SimCenterBackendApplications/blob/master/modules/performRegionalEventSimulation/regionalGroundMotion/FetchOpenSHA.py#L295.

However, please note that the GMM selected in your configuration Json file (Boore et al. (2014)) does not use the hypocenter location, and defining the hypocenter location will not make a difference to the predicted ground motions. The only GMM in R2D that uses the hypocenter location is (Campbell and Bozorgnia (2014)). This GMM uses the depth of the hypocenter, and R2D uses the mean of the upper and lower fault edge depth as the hypocenter depth by default. This is reflected in the code linked above and can be edited if you would like to.

I hope this addresses your questions. Should you have any more questions, please don't hesitate to reach out.

Best,

Jinyan

Hello Bofan,

This is a flaw of the software that the output format of the earthquake simulation tool is different from the input format of R2D HAZ panel. The earthquake simulation tool uses "SA(0.01)" to represent spectral acceleration at 0.01s, while the HAZ panel uses "SA_0.01" (See the input files of R2D example 14 at https://github.com/NHERI-SimCenter/R2DExamples/blob/master/E14BasicHAZUSTransportation/input_data/IMs/S_001_1000.csv for an example) to represent spectral acceleration at 0.01s.

To resolve this issue, please rename the columns in the output of the earthquake simulation tool so the R2D HAZ panel can read the files.

Thank you for catching this error and we will fix this in the future release. We apologize for the confusion.

Best,

Jinyan
